I just received this link to folding kayaks and canoes. Since some of our forum's contributors are water sports enthusiasts, I thought that I would pass it along.

2swans, you might consider selling your kayak canoe and buying one of these folding canoes. The 18 footer weighs 49 lb., only 6 lb. heavier than your present one (since they cost only around $40 per lb., one might have to consider the purchase for a few minutes?). :
